fn set_data(&mut self, data: ByteBufferPtr, _: usize) -> Result<()>
[src]
fn set_data(&mut self, data: ByteBufferPtr, _: usize) -> Result<()>
Sets the data to decode to be data
, which should contain num_values
of values to decode. Read more
fn get(&mut self, buffer: &mut [T::T]) -> Result<usize>
[src]
fn get(&mut self, buffer: &mut [T::T]) -> Result<usize>
